Abstract

The invention discloses a fertilizer synergist, and belongs to the technical field of fertilizers. The method comprises the following steps: placing a chitosan solution, a polyvinyl alcohol solution,a polyethyleneimine water solution, an ammonium chloride solution, a calcium nitrate solution, and modified sepiolite in a material mixing machine, carrying out stirring and mixing for 30-50 minutes at a rotating speed of 100-200 r / min, adding distiller's grains with a mass of 0.3-0.5 time of the mass of the chitosan solution into the material mixing machine, continuing carrying out stirring and mixing for 30-50 minutes at a rotating speed of 100-200 r / min to obtain mixed slurry, putting the mixed slurry into a high-pressure reaction kettle, injecting carbon dioxide into the high-pressure reaction kettle under high pressure by using a pump, then keeping the pressure and carrying out cooling, wherein the pressure is kept to be 10-12 MPa for 10-12 minutes at a temperature of -5 to 10 DEG C,then opening an external pipeline of the high-pressure reaction kettle, and reducing pressure slowly to obtain the fertilizer synergist. The fertilizer synergist provided by the invention is beneficial to plant growth.

Description

technical field [0001] The invention discloses a fertilizer synergist and belongs to the technical field of fertilizers. Background technique [0002] In corn production, the problems of fertilizer waste or insufficient fertilizer efficiency caused by unreasonable fertilization have become increasingly prominent. Nitrogen is the most important limiting factor affecting the high yield of corn, and the absorption of nitrogen in the whole growth period of corn is the largest. At present, the phenomenon of heavy nitrogen, light phosphorus, and neglect of potassium in crop fertilizer application is widespread, which not only seriously affects and restricts the potential of crop yield increase, but also aggravates the loss of nitrogen fertilizer and environmental pollution. Therefore, research on the effects of applying different fertilizer synergists on the basis of chemical fertilizers on corn yield and yield components, nutrient uptake, and changes in corn dry matter accumulati...
